During an interview Tuesday at the residence he shared with his family, his mother said the news of his slaying came as a shock, because there was “not one person he had a problem with.”

“I still don’t believe it,” said Hargrove’s mother, who would only give her first name, Betty.

No arrests have been made in the shooting, and police have not disclosed a possible motive.

Betty said Tuesday that her son leaves a 10-year-old daughter and that he had been laid off from his construction job at the time of his death. She said he enjoyed exercising at a gym and spending time with relatives.

“He loved his family,” she said.

Asked if she had a message for the perpetrator, Betty said: “I don’t know. It’s hard to say right now. I’m still numb. I hope they find somebody.”

Betty said Hargrove divided his time between Boston and Virginia while growing up and eventually obtained his GED. She said a funeral will be held Saturday.

According to a 2006 entry on the official website of the Boston police, an officer attempted to stop Hargrove on Jan. 24 of that year after he committed several traffic violations while driving.

Police said at the time that Hargrove initially refused to stop and “drove into the backyard of 47 Wayland Street [in Dorchester] and jumped from the car. He was quickly caught and a loaded .45-caliber firearm was recovered from the yard.”

Hargrove was charged with unlawful possession of a firearm and ammunition, but it was not clear Tuesday how that case was resolved.

Darrell Holmes, 55, of Dorchester said he comes to the area often to visit family. He said that gunmen in the area seem to operate with impunity.

“It’s crazy, man,” Holmes said. “They be shooting, they don’t care.”

The slaying of Hargrove came two days after a 19-year-old man was fatally shot near the intersection of Norfolk and Clarkwood streets in Mattapan.

Boston police said in a statement that the victim, Walter White of Mattapan, was killed at about 6 p.m. Thursday. His family could not be located for comment. As in the Hargrove case, no arrests have been made, and police have not commented on a possible motive.

“We are continuing to ask for the public’s help,” Cheryl Fiandaca, a Boston police spokeswoman, said in e-mail. “Anyone who may have seen or heard anything in connection with these incidents is urged to contact” police.

There have been 35 homicides in Boston this year, compared with 37 at this time in 2012, according to police statistics.
